Have you any proof of threatening by Bank? What is the mode of such threatening  over phone or by any letter? Let me know by return to give you appropriate advise.

If your father is alive and you have not signed any documents as, say, a surety it is entirely for your father to settle his debts. Only you have to be careful that your father does not, through some misrepresentation, get you also involved. Though such an action on the part of your father may be fraudulent unnecessarily you will have to fight.

The bank or anyone cannot seize your property until you have signed as a surety or co-applicant to the loans availed by your father.  The bankers cannot take away the property on your mother also since she also never stood as a guarantor to your father for his loan.  Let the bank take action, you challenge the case appropriately in the court.   Preserve the records of threats issued by bankers in this regard and initiate proper legal action against them if they do not stop indulging into such illegal acts against you.
